Physics with some crayon

Isn't this game incredibly cool, check the video below. Looks like you really need to know your physics well to play this one :) This one is from Kloonigames and runs on the tablet PC. A PC version of crayon physics is coming soon.



The user experience on this is incredible, watch how the game reacts as the user draws different figures and tries to achieve their objective. With the Wii and PS3 giving PC games a run for their money, I think innovative concepts like this one are a really good answer.

Wow tube

The video player user experience in YouTube is probably single biggest contributor to its explosive adoption.

By the time the one video that you came to see ends, a very very smart engine keep egging you to seem more and more untill you are hooked.

The uncluttered screen layout presents the most obvious options. Share and the replay being the first choice of actions. Scrollable other similar videos being the second and only other choice.

Simple and (hence?) effective
